When IgG4-TIN is accompanied by other systemic manifestations the disease is known as IgG4-related systemic disease (IgG4-RSD). IgG4-RSD is well recognised in the form of tubulointerstitial nephritis (IgG4-related TIN) and may present with renal failure by mimicking neoplasms (tumefactive lesions) or with both features. We describe a case of IgG4-RSD initially presenting as a submandibular mass and subsequently presenting two years later with secondary infiltration of the kidney causing tubulointerstitial nephritis. This case highlights the importance of recognising IgG4-RSD as a non-malignant disease with presentations having commonly shared features including tumour-like swelling of involved organs and its ability to mimic many systemic diseases. In the majority of patients it can be treated successfully with corticosteroids.<\/jats:p>","DOI":"10.4997\/jrcpe.2014.206","type":"journal-article","created":{"date-parts":[[2014,7,8]],"date-time":"2014-07-08T05:46:51Z","timestamp":1404798411000},"page":"122-125","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["A Masquerading Mass: An Unusual Presentation of IgG4-Related Systemic Disease with Tubulo-Interstitial Nephritis"],"prefix":"10.1177","volume":"44","author":[{"given":"B","family":"Quinn","sequence":"first","affiliation":[{"name":"Foundation Year 2 doctor, Daisy Hill Hospital, Newry, Northern Ireland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J","family":"Harty","sequence":"additional","affiliation":[{"name":"Consultant Nephrologist, Daisy Hill Hospital, Newry, Northern Ireland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W","family":"Habeichi","sequence":"additional","affiliation":[{"name":"Specialist registrar, Daisy Hill Hospital, Newry, Northern Ireland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,6]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200103083441005"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/PAP.0b013e3181ee63ce"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra1104650"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e3181c811ad"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/232960"},{"key":"e_1_2_1_7_2","first-page":"56","article-title":"K\u00fcttner's tumour: an unusual cause of salivary gland enlargement","volume":"12","author":"Kivernti E","year":"2008","unstructured":"KiverntiE, SinghA, ClarkeP.
